Import new tags for noise, green and water feature

• A PostgreSQL and a osm2pgsql installation is needed see https://www.postgresql.org/ and https://osm2pgsql.org/

• and a jdbc driver see https://jdbc.postgresql.org/download/

• prepare database

# postgres createdb --encoding=UTF8 -U postgres osm

# postgres psql -U postgres osm --command='CREATE EXTENSION postgis;'

• import to database and create

# osm2pgsql -c -s -d osm -U postgres -W -H localhost -P 5432 -O flex -S brouter_cfg.lua /path/to/file.pbf

• generate new tags inside the database (use < if -f does not work)

# postgres psql -d osm -U postgres -f brouter.sql

• prepare generation of pbf

  • lookups.dat has to contain the new tags from the database

  • script needs a jdbc in the classpath (on UNIX and Linux use a colon : as delimiter)

    ... -cp ../postgresql-42.6.0.jar;../brouter_fc.jar ...

  • script needs a call with jdbc parameter

    define the database parameter

    JDBC="jdbc:postgresql://localhost/osm?user=postgres&password=xyz&ssl=false"

  • export the tags from database to filesystem

    java -Xmx6144M -Xms6144M -Xms6144M -cp %CLASSPATH% btools.mapcreator.DatabasePseudoTagProvider $(JDBC) db_tags.csv.gz

  • call it with OsmFastCutter as last parameter (behind pbf file)

    ... btools.mapcreator.OsmFastCutter ... ../planet-new.osm.pbf db_tags.csv.gz
